Usage Guidelines
Cisco Discovery Protocol (CDP) is a protocol by which one Cisco device can
recognize, and be recognized by, another Cisco device. The run command sta rts
the system sending out signals to the other systems. The timer command sets the
amount of time, in seconds, that these signals are sent. The holdtime sets the
amount of time a system will recognize another system without receivi ng a signal.
For example, if your system’s holdtime is set to 30 seconds, and another system
that has already been recognized by yours does not send a signal withi n t hat
30 seconds, your system will cease to recognize it. If you are using the no cdp
command, the timer and holdtime commands set their respective values to the
default value.
Example
This command sets the cdp packet’s retransmission time at 10 seconds.
